20lb mono would work well for those swimbaits. Slower is usually better and clear water is a plus. Hardcore swimbait guys will tell you to throw them 24/7, it's a lifestyle for them. Pick out high percentage areas and take your time fishing them. I see you have all slow sink or floaters. Maybe add a faster sinking soft bait to get down to the bottom to slow roll/drag if your fishing deeper weedlines, points, etc. Just a thought.
